Primary tooth stage (1-6 years old)
Problems: uneven teeth, skeletal dysplasia, bad habits.
Measures: Simple irregular teeth do not need to be corrected. However, for the gap caused by early deciduous teeth falling off, it is necessary to seek medical advice in time to prevent malocclusion in the future.
Bone and tooth malocclusion should be treated as soon as possible, which will inhibit the development of maxilla and form a depression in the middle of the face, and the child will be nicknamed by classmates, which will affect mental health; In addition, malocclusion will affect the symmetrical development of jaw and temporomandibular joint, and eventually lead to the asymmetry of bone, commonly known as crooked chin.
Because of bad oral habits, such as sucking your fingers, biting hard objects, biting your lower lip, sticking out your tongue, breathing through your mouth, etc., you should seek medical advice as soon as possible and get rid of bad habits.
Tooth changing period (6- 12 years old)
Problem: The symptoms such as the gap between the central incisors and tooth torsion have entered the stage of "ugly duckling".
Measures: It is not surprising that there is a gap of less than 2mm between the upper incisors. However, if the gap is too large, turn the upper lip up and lift it up gently, and you can see that there is a "ligament" at the midline-the upper lip frenulum, which is sometimes too long and extends down between the two central incisors, so that the two teeth cannot be closed together.
If a small lacing operation is done earlier and the attachment point of lacing is moved up, there will be no gap between the two erupted central incisors. This minor operation can be completed before changing teeth.
Simple tooth irregularity does not need to be corrected at this stage, but the growth and improvement of skeletal malocclusion such as maxillary retraction and mandibular retraction must seize the opportunity. Mandibular retraction deformity should be corrected by bone improvement before the peak of children's growth and development.
Because girls develop earlier than boys, the peak of growth and development is girls10-1year, boys 12- 13 years. Maxillary retraction deformity should be corrected at the age of 8- 10. In addition, special intervention can avoid tooth extraction before the child's second big die erupts.
Permanent dentition (/kloc-after 0/2 years old)
Comprehensive correction after the formation of permanent dentition can correct tooth dislocation and establish a good relationship between tooth arrangement and cusp fossa. All kinds of malocclusion can be treated comprehensively and systematically during this period. In adolescence, because children still have certain growth potential, they respond quickly to the restoration and reconstruction of orthodontic treatment, move their teeth quickly, have little pain, have a short course of treatment and have high treatment efficiency.
